A type declares a method with a string parameter whose name contains "uri", "Uri", "urn", "Urn", "url", or "Url"; and the type does not declare a corresponding overload that takes a System.Uri parameter.

This rule splits the parameter name into tokens based on the camel casing convention and checks whether each token equals "uri", "Uri", "urn", "Urn", "url", or "Url". If there is a match, the rule assumes that the parameter represents a uniform resource identifier (URI). A string representation of a URI is prone to parsing and encoding errors, and can lead to security vulnerabilities. If a method takes a string representation of a URI, a corresponding overload should be provided that takes an instance of the Uri class, which provides these services in a safe and secure manner.

To fix a violation of this rule, change the parameter to a Uri type; this is a breaking change. Alternately, provide an overload of the method which takes a Uri parameter; this is a non-breaking change.
